Most of the issuers were non-filers. Not delinquent filers.
Good for you on retirement. I am a bug smasher pilot, but I do have jet time. Lear 24 and Lear 35/36. Falcon 20 goes way back like the Lear 24. It is a relic, lol, no offense. How is your hearing?
Did those companies previously file and then become delinquent or were they non-filers from the beginning?
I don't know whether any were delinquent filers. I didn't check them all. But a few had voluntarily deregistered. One of them, MBAY, was once a Nadaq issue. Most, however, were just Pinks.
